Philadelphia, Pennsylvania
At the Subaru Cherry Blossom Festival of Greater Philadelphia (April 7 to 15), held in Fairmount Park, you can admire 1,000 cherry trees. Stop by the Shofuso Japanese House and Garden and you'll feel like you're in the Land of the Rising Sun. The event also pays homage to a historic gift: in 1926, the Japanese government donated cherry trees to commemorate the sesquicentennial (150th anniversary) of American independence.
